1 Claim. 1

The present invention relates to improved ways and means whereby the forward end of a shoulder-type sling may be satisfactorily fastened with the barrel of a rifle, for example, a Remington Gamemaster which has, as is well known, a so-called slide action.

Shoulder straps and slings have, for the most part, been omitted on slide action rifles because satisfactory means for attaching the forward end of the strap to the rifle has, evidently, not been either properly or adequately devised and used. There is nevertheless a great demand for a carrying and holding sling on a slide action rifle. It follows that the object of the instant invention is to provide a swivel which is attachable to the forward end of the sling and has readily applicable and removable means whereby said swivel may be detachably and swivelly connected directly with the barrel of the rifle.

Briefly summarized, a preferred embodiment of the invention is characterized by a ring to which the forward looped end of the sling or shoulder strap is connected, a swivel pin to which the ring is pivotally connected, a mount which is applicable to the barrel, clamping means for the mount, said mount being provided with a socket into which said swivel pin is removably and swivelly fitted.

More specifically, the invention has to do with a mount which not only has socket means for the swivel pin but is also provided with a readily accessible and actuatable spring-held manually released latch, said swivel pin having a keeper with which said latch is cooperable.

In addition to the above novelty is predicated on a mount of general block-like form carrying the stated socket means and latch means, a U-shaped saddle or yoke which is applicable to the barrel and a nut for clamping the yoke in position and also clamping the block-like mount against the barrel through the aid of the yoke.

Other objects, features and advantages will become more readily apparent from the following description and the accompanying sheet of drawings.

In the accompanying drawings, wherein like numerals are employed to designate like parts throughout the same:

Figure 1 is a view in elevation showing a fragmentary portion of a rifle barrel and showing, primarily, the swivel unit and the clamped-ontype adapter means through the medium of which the swivel means is operatively mounted on the barrel;

Figure 2 is an enlarged fragmentary elevational and sectional view taken approximately on the vertical line 2-2 of Figure 3 looking in the direction of the arrows;

Figure 3 is a section on the line 33 of Figure 1 looking in the direction of the arrows;

Figure 4 is a top plan view, with portions broken away, of the part of the adapter means hereinafter referred to as the mount;

Figure 5 is a section on a horizontal line 55 of Figure 3 looking in the direction of the arrows; and

Figure 6 is a view in section and elevation of the swivel unit or means.

Under ordinary circumstances rifles which are provided with so-called sling straps and shoulder straps are provided at the butt end of the stock with an attaching swivel and a similar swivel is provided at the relatively fixed forward end portion of the stock, that portion of the latter which accommodates and underlies the barrel. Corresponding shoulder straps have been omitted from slide action rifies because of the lack of satisfactory provisions for fastening the forward end of the sling or shoulder strap to the rifle. This, however, can be taken care of, as is herein revealed, by way of a suitable adapter which applies directly to the barrel itself and which has incorporated therein socket means for a swivel pin.

Reference is had first to Figure 6, which shows the swivel means or unit. This means, in a unitary sense, is denoted by the numeral 8. Like most swivels for gun slings it is characterized by a swivel pin in and a sling strap attaching ring I2. The latter is generally rectangular in form and is hingedly or pivotally attached to one end of the pin. The opposite end of the pin is grooved as at M to provide a swivelling and keeper head. The sling strap (not shown) has one end looped through the ring [2 and thus attached to the pin. It remains, therefore, to provide satisfactory structural adapter means for detachably and swivelly joining the swivel pin directly to the barrel it of the rifle. While other clamping devices and mounts could be employed to achieve this end the specific one herein shown as a preferred embodiment is characterized by a unit which is called a mount, generally speaking, and is denoted by the numeral Hi. This is of block-like form. Because it includes latch means it is preferably made up of companion sections. That is to say, there is an elongated rectangular base or primary section 29 which has spaced parallel flanges 22--22 which embrace diametrically opposite sides of the rifle barrel in the manner shown best in Figures 1 to 3, inclusive. This section also has a channel 24 which opens through opposite ends thereof as shown best in Fi ures 2 and 4. There is a secondary section 23 which is rectangular and is, therefore, a block-like insert and this is fitted into the channel 24 and held therein by screws or other equivalent fasteners 28 much in the manner illustrated in Figure 4. The bottom of the channel 24 has recess means 30 and 32 to accommodate a manually actuatable spring-returned latch. The finger-piece of the latch is denoted at 34 and the latch head proper is denoted at 36 and this is slidable in the recess 39 and has a keyhole slot 38 which obviously is engageable with the grooved end or head it of the swivel pin II) in an evident manner. There is a stem or extension 40 on the latch plate which operates in the groove 32 and there is also a coil spring 42 provided and this spring serves to normally keep the keyhole slot and latch in the position shown in Figure 4 which is a locking position. The primary section 29 has a central depending neck or extension 44 which has a central passage therethrough forming a socket 45 for the swivel pin. It follows that by fitting the swivel pin into the socket 46 and then releasing the latch, that is, the finger-piece 34 thereof, the latch plate 36 engages the keyhole slot with the keeper means 14 of the swivel in It thus holding the pin in the socket for swivelling operation. This sectional mount and swivel unit 8 are both applied to and clamped on the rifle barrel and this is accomplished by an inverted U-shaped yoke 43 which is fitted over the barrel and has spaced parallel arms 50-59 on diametrically opposite sides terminating in screw-threaded end portions I. These depend along opposite longitudinal sides of the section 20 of the mount where they serve to accommodate a suitably knurled nut 52 whose threads 54 engage with the threads on said threaded end portions 5 i. Thus saddling the yoke over the rifle barrel and applying the nut 52, the nut clamps against the bottom of the mount and secures the mount efl'ectively so that the flanges 22- 22 bind against the barrel in the manner best shown in Figures 1 and 3.

Briefly reviewed the mount [8 is of rectangular block-like form and has a neck 44 with a socket 46 to accommodate the insertable and removable swivelling pin Ill which pin is provided with a ring or the like I2 to accommodate the looped end of the sling strap (not shown). By saddling the yoke over the rifle barrel and applying the nut the mount is effectively clamped on the barrel.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a more lengthy description is regarded as unnecessary.

Minor changes in shape, size and arrangement of details coming within the field of invention claimed may be resorted to in actual practice, if desired.

Having described the claimed as new is:

A gun sling swivel and an attachment therefor removably applicable to the barrel of a rifle comprising, a block-like elongate mount having a surface conformable with and adapted to bear lengthwise directly against the stated gun barrel, said mount embodying an axially bored neck providing a socket member for reception of an insertable and removable swivelling pin, a swivelling pin fitted removabiy in said socket member and having a strap loop hinged on one end, the other end of said pin being marginally grooved and providing a keeper head, a spring pressed latch operatively mounted in said mount and re. sably engaging said keeper head, a U-shaped clamp adapted to clampingly embrace the stated gun barrel, said clamp having arms adapted for disposition on opposite sides of the barrel and having screw-threaded portions situated on opposite intermediate longitudinal sides of said mount, and a readily applicable and removable assembling and clam-ping nut screwed on said screw-threaded portions and situated beneath and having direct clamping contact with said mount and encircling said socket member.
